RING SPINNING OR TWISTINC- APPARATUS.

Specification of Letters Patent.

Patented April 30, 190'7.

Application led October 3, 1906. Serial No. 337.231.

T0 @ZZ whom it may concer/t.'

Be it known that I, GEORGE W. iNIGnr, a citizen oi the United States, residing at ilo pedale, county of Worcester, and State oi tiassachusetts, have invented an improvement in Ring Spinning or Twisting Apparatus, oli which the following description, in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts.

`This invention relates to spinning or twisting apparatus wherein the yarn is led to the rotating spindle through or from a traveler revoluble on a ring, and my invention has for its object the production of novel and ellicient means for cushioning the ring with relation toits holder, whereby, under the variations due to unbalanced load, yarn tensions or improper centering of the spindle, slight axial or lateral movement oi the ring is permitted and-such movement cushioned.

The invention does not belong to the socalled rotary ring type of apparatus wherein the essence ol the structure is a free rotation of the ring at all times when the apparatus is in motion, but as will hereinafter appear the ring in my present invention may or may not rotate, according` to the various exigeneies of operation.

The novel features ofiny invention will be fully described in the subjoined speciiication and particularly pointed out in the `iollowing claims.

Figure 1 is a diametre-l section on the line 1--1, Fig. 2, of a spinning or twisting ring and cushioned ring-holder embodying one form of my present invention; Eig. 2 is a partial top plan view thereof, the ring and downhold being broken out to show the ring seat and the cushioning means; Fig. 3 is a detail enlarged, in side elevation of the ring-helder and ring; and Fig. 4L is a diametral section thereof similar to F ig. 1 but much enlarged.

I have herein shown the ring as oi a well known type, having upper and lower circular' ilanges 1, 2, connected by a cylindrical web 3, and technically termed as a double-flanged ring, the uppermost ila-nge serving in usual manner as a raceway for the traveler.

In the presen tembodiment oi my invention I have shown the ring-holder as comprising a cylindrical or tubular body ii having a laterally extended circular head 5 which rests upon the ring-rail lt, see Fig. 1, the body -il depending through the usual hole in the rail, Vthe spindle, (not shown) passing up through the body ol the holder.

The ring-holder is provided with an annular ring-seat (i having an outer circular side wall 7, and the top et the head 5 is also provided 4with a shallow and concentric seat or recess S. The ring-seat has pressed or inserted in it a cushion or lining S) ot suitable non-metallic material, ysuch as thin leather, rubber, etc., which will serve as a cushion for the ring, such lining or cushion covering the seat and being upturned against the side wall 7, as clearly shown at 1() in Figs. 1 and 4, and partly in Fig. 2.

Hthin the lined or cushioned seat the lower i'lange 2 ol'` the ring is inserted, not with a tight and immovable lit, but with sullicient ease or looseness to permit slight axial and radial movement oi" the ring, and at times even some rotative movement. it will be manifest that the bottom of the ring is cushioned, and also the edge or periphery of the base `ilange, thereby preventing any shock or jar to the ring when it is moved either axially or vertically.

The ring-holder has a down-hold to limit vertical ring movement, and herein the downhold is shown as two semi-circular metallic segments 11, held in place by screws 12 or other fastenings passed through the head 5 and into the segments.

A thin washer-like cushion 13 et' leather or other-suitable material is laid in the recess S and irs inner portion extends over and above the 'flange 2 of the ring, as shown, the downhold retaining said ring-like cushion in place, and thereby cushioning the top oi the ilange when the ring is lifted.

As shown in Figs. 1 and 4 the inner edge oi the downhold extends far enough over the ring flange to retain the ring on the holder, the iastenings 12 in practice passing through holes made in the cushion 13.

By the construction herein shown and described the ring is securely retained in position on the ring-holder, yet it is eil'ectually cushioned against any shock or jar which would result -from the metal surface of the ring striking against any metallic. surface on the ring-holder. I am, by cushioning the ring, enabled to secure a very smooth action,

IOO

free from all jar or shock, when the apparatus is in use, resulting in better spinning or twisting of the yarn7 and reducing yarn breakage.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is l. A ring-holder having an annular seat, a non-metallic lining for and resting against the bottom and outer wall of the seat, and a ring having a flange supported on the lining and vertically and laterally cushioned thereby.

2. The combination, with a ring-holder l having an annular seat and a downhold, a continuous cushion lining the bottom and side wall of the seat, a ring having a flange loosely resting in the Cushioned seat, and a cushion overhanging the seat and interposed between the downhold and the top of the ring flange.

In testimony whereof I have signed my naine to this specification, in the presence of two subscribing witnesses.
